Pleurae and Pleural Cavities Flashcards
What are the 3 cavities that the thoracic cavity is subdivided into
2 pleaural cavities
1 mediastinum
What is located in the pleural cavity surround
The lungs
How does the pleural membrane become the visceral pleura
Folds in at the root of the lung to make a second layer
What is the plaural cavity
It is a potential space between parietal and visceral pleuae
What lubricates the plaurae.
Pleural fluid
What are the 4 parts of the parietal pleura
Costal Pleura
Mediastinal pleura
Diaphragmatic Pleura
Cervical PLeura
What are the spaces between the two folds of parietal pleura
Pleural Recesses
What are the two pleural recesses
Costodiaphragmatic recess
Costomediastinal recess
where is the Costodiaphragmatic recess
where the costal and diaphragmatic pleurae meet
Which pleural recess tends to have fluid accumulate in it?
Costodiaphragmatic recess
How and where can you get fluid from the costodiaphragmatic recess removed
Removal: Thoracentesis
Where: top of Costal interspace 9
What arteries supply the parietal pleura
Intercostal arteries
Internal thoracic artery
Superior phrenic artery
What arteries supply the Visceral pleura
Bronchial artery
What innervates the parietal pleura
Intercostal nerves
Subcostal nerve
Phrenic nerve
What innervates the visceral pleura
none
Which pleural membrane is sensitive to pain
Parietal pleura
Condition in which the pleural cavity it filled with air
Pneumothorax
What can cause Pneumothorax
Trauma (a.k.a Sucking Chest Wound)
Disease
What are the two types of pneumothorax
Simple pneumothorax
Tension pneumothorax
What is simple pneumothorax
Hole in membrane (visceral pleura)
Air goes into pleura cavity on inspiration and some goes out on expiration
What is Tension pneumothorax
There is a flap on the visceral pleura
Air goes into cavity, but cant escape
Pleural cavity inflates and can compress the other lung
Which type of pneumothorax is life threatening
Tension pneumothorax
What is Hemothorax
The pleural cavity fills with blood
What is Hemopneumothorax
The pleural cavity fills with blood and air
What is a collapsed lung
Atelectasis
what is pleuritis
inflamation of the pleurae membrane(s)
What can pleuritis lead to
Adhesions between parietal and visceral pleurae
Is there refered pain associated with pleuritis? Where will it be found and what nerves are associtated
Yes there will be refered pain
Pain: in the shoulder
nerve: phrenic nerve (C3 C4 C5)
Where will pain radiate in pleuritis
Along the distribution of the supraclavicular nerve (C3 C4)
What is the sound made from pleuritis. (herd during ausculation)
Friction Rub
